A small C11 utility that converts FAT12 filesystems into FAT16.
fat12conv does not have any dependencies.
fat12conv INPUT OUTPUT
INPUT is the FAT12 filesystem to convert, and OUTPUT is where the
FAT16 filesystem will be written. In-place conversion is not supported.
To convert actual disks, use /dev/<disk> as INPUT and a temporary file
as output, then use dd to copy the output back to the disk.
fat12conv can be built like any other CMake project:
mkdir build
cd build
cmake ..
cmake --build .
